The flagship Mercedes-AMG GT 4 Door super-limo may have a 470kW/900Nm V8 punch, and reach 100km/h in only 3.2 seconds, but a plug-in hybrid model due in 2020 will make it look slow.

Daimler AG boss, Dieter Zetsche, dropped the news an EQ Power+ badged plug-in hybrid version of AMG's new hero was coming. We were lucky enough to have Mercedes-AMG boss, Tobias Moers, expand on that for us.

He told us to look at the Mercedes-AMG GT concept – revealed at the 2017 Geneva motor show – telling us brusquely the plug-in model would be “that”.

The concept ran with a familiar AMG 4.0-litre V8 bi-turbo engine backed by an electric motor, with an (early development) system output of about 600kW enabling a sub-three second 100km/h sprint time.
